It does <br /> not, nor is it intended to, describe the factual and scientific basis for the findings and conclusions set <br /> forth, nor does it describe past work performed at the site, or the geological, hydrological or other <br /> characteristics of the site, where such matters have been described in other reports. ANY PARTIES <br /> INTERESTED IN THE SITE REMEDIATION ARE CAUTIONED TO REVIEW THE REPORT IN FULL FOR <br /> ALL PARTICULARS ABOUT THE SITE CONDITIONS PILOT TESTING WORK AND RECOMMENDED <br /> REMEDIATION TECHNOLOGIES. . <br /> The objective of the work performed by Groundwater Technology, Inc., and described in the Report (the <br /> "Pilot Testing Work") was to further quantify groundwater and soil vaporflow characteristics under <br /> various vacuum and pumping influences to determine a cost effective remedial action technology <br /> appropriate for removal of gasoline and diesel fuel hydrocarbons detected in the soil and.groundwater at <br /> the site. <br /> The Pilot Testing Work had essentially four components: <br /> i) Installing one extraction well and three observation wells for the purposes of conducting <br /> the pilot testing described below; <br /> ii) performing a constant-rate aquifer test (which involved groundwater pumping only); <br /> i iii) performing a combined groundwater extraction and high-vacuum soil vapor extraction <br /> (HVE) test (which involved pumping groundwater from the extraction well using a <br /> r centrifugal pump and applying a vacuum to the well to extract soil vapors and enhance <br /> groundwater flow from the well); and <br /> iv) performing a high-vacuum dual-phase extraction (HVDPE) test (which involved applying <br /> a vacuum to the well to extract both soil vapors and groundwater from the well). <br /> I <br /> GROUNDWATER <br /> '71�! - _i TECHNOLOGY, INC. <br /> i <br />
